Instead of ‘int’ or ‘uint32_t’, neither of which convey much meaning,
consistently use a newly added type to hold NDR_ flags.
Update the NDR 4.0.0 ABI.

WACK packets use the ‘data’ member of the ‘nbt_rdata’ union, but they
claim to be a different type — NBT_QTYPE_NETBIOS — than would normally
be used with that union member. This means that if rr_type is equal to
NBT_QTYPE_NETBIOS, ndr_push_nbt_res_rec() has to guess which type the
structure really is by examining the data member. However, if the
structure is actually of a different type, that union member will not be
valid and accessing it will invoke undefined behaviour.
To fix this, eliminate all the guesswork and introduce a new type,
NBT_QTYPE_WACK, which can never appear on the wire, and which indicates
that although the ‘data’ union member should be used, the wire type is
actually NBT_QTYPE_NETBIOS.
This means that as far as NDR is concerned, the ‘netbios’ member of the
‘nbt_rdata’ union will consistently be used for all NBT_QTYPE_NETBIOS
structures; we shall no longer access the wrong member of the union.

Add new for_selftest option to SAMBA_BINARY() and SAMBA3_BINARY()
This allows us to be much more consistent (at least in the core Samba)
and documents clearly why the binary should not be installed.
Not modified are
- test_lp_load
- notifyd-tests
- gendrandperf
- test* from examples/libsmbclient
- dbwrap_torture
- split_tokens
- locktest2
- msgtest
- msg_sink
- msg_source
- versiontest
- rpc_open_tcp
- test_headers
As these are not tested in selftest so any change would also be
untested. Of course they probably should be added in a different
MR.
Also not modified (because they are not tests, nor part of the
build system) are:
- smb2mount
- notifydd
- log2pacp
- debug2html
- smbfilter
- destroy_netlogon_creds_cli
- spotlight2*
- tevent_glib_tracker
These do however appear to be untested.
For now, the source4 forked client tools are left unchanged:
- smbclient4
- nmblookup4
Finally, the heimdal binaries are left as install=False as
they are either part of the build system or end-user tools
that we just don't want to install. These are however tested.
The motivation is commit like c34ec003b7
and da87fa998a, which are both totally
correct but are not needed if the selftest is not run on MacOS.
There are likely other platforms or build environments where building
our test binaries is more pain than valuable, see for example also

With the changes to make samba python code Py2/Py3 compatible there
now are many instances where string content is decoded.
Decoded string variables in Py2 are returned as the unicode type. Many
Py2 c-module functions that take string arguments only check for the
string type. However now it's quite possibe the content formally passed
as a string argument is now passed as unicode after being decoded,
such arguments are rejected and code can fail subtly. This only affects
places where the type is directly checked e.g. via PyStr_Check etc.
arguments that are parsed by ParseTuple* functions generally already
accept both string and unicode (if 's', 'z', 's*' format specifiers
are used)
